Inventor 9 By Y i5 v' Sag-ff Attorney Patented Dec. 18,- l934 UNITED STATES PATENT OFFICE AGITATOR William B. Lodder, Syracuse, N. Y.

Application September 27, 1934, Serial No. 745,799

8 Claims. (Cl. 259-102) This invention appertains to new and useful improvements in the general art oi agitating and more particularly to a novel agitator especially adapted for agitating materials such as poisons l and acids with which it is undesirable and danger- `ous to come in contact.

The principal object of the present invention is to provide an agitator wherein the material is agitated in a container without any manual effort 10 and without any likelihood of the material being displaced in any part.

Other important objects and advantages of the invention will become apparent to the reader oi Lthe following specication.

15 In the drawings:

Figure 1 is a vertical sectional view through one form of the invention.

Figure 2 is a horizontal sectional view taken substantially on line 2-2 of Figure l.

. 20 Figure 3 is a vertical sectional view through a second form of the invention.

Figure 4 is a diagrammatic view disclosing the electrical connections between the electrical elements involved.

25 Figure 5 is a vertical sectional view through a third form of the invention.

Figure 8 is a horizontal sectional view taken substantially on line 6-6 of Figure 5.

Referring to the drawings wherein like numerals 30 designate like parts, it can be seen that in each iorrn f the invention a container is employed. this container in Figure l being denoted by numeral and being provided with a screw insert cap 6.

35 Threaded into and depending from this cap 6 is the conduit 7 for the electrical cable 8. This conduit 'l connects to the shell 9 at its lower end, thus suspending the shell in the manner substantially shown in Figure 1. As is clearly shown in Figures 40 1 and 2, a radial arrangement of electro-magnets is provided in this shell 9. A trough il, notched at intervals to provide the teeth 5, extends around the perimeter of the shell 9 and contains one or more metallic balls 13.

By referring to Figure 4, it can be seen that by employing a current distributor generally referred to by numeral 14 and connecting the contacts thereof up with the magnet i0 and grounding the opposite sides of the magnet, current will 50' be successively supplied to the magnet and in this successive energization of the magnet the ball 13 will be caused to travel around the trough and result in the agitation of any material contained in the receptacle 5.

55 Figure 3 shows the same form of receptacle denoted by numeral 5' and this has a cap 6' of like construction 'excepting that a di-electric bushing 7' is provided in the cap 6' through which the cable 8 snugly iits.

'I'he shell 9' containing the magnet 10' is supported by legs l5 the trough l1' and ball 13' being provided in the same capacity as in the iorm of the invention shown in Figure 1, the chief difference being in the manner of supporting the shell 9'.

Figure 5 shows another form of the invention which consists of the receptacle 5a having the removable screw insert cap 6a. Numeral 7a represents a conical shaped raised portion in the bottom of the receptacle and around this is provided several troughs lla--lla vertically notched to provide teeth 12a. These troughs contain balls 13a. Shells 9ct- 9a are provided on the inside of the conical formation 7a in corresponding relation to the troughs 11a-11a, these shells containing the radial arrangement of magnets 10a.

While the foregoing specification sets forth the invention in speciiic terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. An agitator comprising a receptacle, a shell in the receptacle provided with a radial arrangement of electro-magnets therein, a trough at the perimeter oi the shell, a roller in the trough, and means ior supporting the shell in the receptacle.

2. An agitator comprising a receptacle, a shell in the receptacle provided with a radial arrange ment of electro-magnets therein, a trough at the perimeter oi the shell. a roller in the trough, and means for supporting the shell in the receptacle, said shell being provided with a removable top, and a conduit extending from the said top to form a means for supporting the said shell and serving as a protector ior conductors to the electro-magnet.

3. An agitator comprising a receptacle, a shell in the receptacle provided with a radial arrangement oi electro-magnets therein, a trough at the perimeter of the shell, a roller in the trough, and means for supporting the shell in the receptacle, said means for supporting the trough consisting in providing an upstanding formation in the bottom oi the receptacle and securing the said trough upon this portion of the receptacle bottom, said shell being mounted in the said upstandlng portion oi' the bottom.
